Abstract

DNA profiling has been assuming a prominent role in the activities of the criminal justice system. Genetic technologies support criminal investigations, while also being seen as holding a highly valuable potential for producing evidence to be used in courts. This chapter has two main objectives: on the one hand, to describe and explain the ways that DNA technologies can be used in criminal investigation and turned into DNA evidence in criminal proceedings; on the other hand, this chapter aims to systematize the main lines of academic literature within the social sciences which have been developed to study the social implications and transformations of cultures and professional practices arising from the presence of DNA technology in the criminal justice system. Besides, the chapter also pays particular attention to the social nature of the high expectations associated to the ``infallibility'' of DNA technologies and how the media portrays the use of forensic genetics and further exacerbates such notions.
